Answer:

The equivalent expression to the given expression is the option B;

B. 6(7 + 15)

Step-by-step explanation:

The given expression is 42 + 90,

We note that an equivalent expression, is one that can be substituted by the original expression or one with equivalent value.

Therefore, we have, for the first expression;

A. 6 × (7 + 14) = 6 × 23 = 138

For the second option, we have;

B. 6 × (7 + 15) = 6 × 22 = 132

For the third option, we have;

C. 7 × (6 + 12) = 7 × 18 = 126

For the third option, we have;

D. 6 × (36 + 84) = 6 × 120 = 720

Also we note that the value of the given expression is 42 + 90 = 132, therefore, the equivalent expression to the given expression is option B. 6(7 + 15).

mars1129 [50]

Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

=684sq cm

cost required to make umbrella= 10*684*5

= 3<em>4200</em>
