Area of kite is 1/2 times the two diagonals.
So, it would be 1/2 times 70 times 70.
Solve it and you get 2450.

The answer is 2450 square cm.
But the question is asking for meters so convert it.
1 cm is 0.01 in meters. 2450 times 0.01 equals 24.5 meters
24.5 square meters is your final answer.

Solve for x: 5x + 6 = 8x + 12

ICE Princess25 [194]

Answer:

x=-2

Step-by-step explanation:

Step 1: Subtract 8x from both sides.

5x+6−8x=8x+12−8x

−3x+6=12

Step 2: Subtract 6 from both sides.

−3x+6−6=12−6

−3x=6

Step 3: Divide both sides by -3.

−3x

−3

x=−2

If the basketball player scored 15 baskets out of 21 tries. How many tries would it take to score 20 baskets?

Evgen [1.6K]

28 tries. The ratio is 5:7, so once you multiply 5 by 4 to get 20, you do the same to 7 to get 28.

PLEASE SOLVE AND CHECK. SHOW COMPLETE SOLUTION

Alex17521 [72]

Solution:

$\sqrt{4x + 13} = x + 2$

First square both sides.

$= > ( \sqrt{4x + 13} ) ^{2} = (x + 2) ^{2}$

Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².

$= > 4x + 13 = {(x)}^{2} + 2 \times x \times 2 + (2) ^{2} \\ = > 4x + 13 = {x}^{2} + 4x + 4$

Now, transpose 4x and 4 to LHS.

$= > 4x - 4x + 13 - 4 = {x}^{2} \\$

Now, do the addition and subtraction.

$= > {x}^{2} = 9 \\ = > x = \sqrt{9} \\ = > x = ±3$

Answer:

x = ± 3
