Answer:
42cm²
Step-by-step explanation:
It is actually 7cm by 6cm
You are taking 2 x 0.5cm of the smaller sides rectangles which is 1. This leaves us with 6 x 7 = 42cm²
4/9 + 1/5 (common denominator is 45)
20/45 + 9/45 = 29/45
Answer:
3
Step-by-step explanation:
15 divided by 5 equals 3.
Hey there,
<span>Ok 72^3
</span>First, find out what numbers can multiply to equal 72
<span>√72 = √9*8 </span>
<span>Then find other numbers which can be squarerooted and will get you a whole number </span>
<span>= √9*4*2 </span>
<span>= √9 * √4 * √2 </span>
<span>= 3* 2 * √2 </span>
<span>=6n√2
</span>
Sorry almost forgot about the N hope this help mark brainlyist if can l8tr!!!
Answer:
<em>(16.2t+3.4u+2.9)cm</em>
Step-by-step explanation:
A triangle is a plane shape that has three sides. <em>The perimeter of a triangle is gotten by taking the sum of all the lengths of the three sides</em>. Let the length of the three sides by s1, s2 and s3, the perimeter of the triangle will be expressed as;
P = s1+s2+s3
Given the side lengths
s1 = (8.1t-6.1)cm
s2 = (8.1t+7.1)cm
s3 = (3.4u+1.9)cm
Perimeter of the triangle = 8.1t-6.1+8.1t+7.1+3.4u+1.9
collect the like terms
P = 8.1t+8.1t+3.4u-6.1+7.1+1.9
P = 16.2t+3.4u+2.9
<em>Hence the expression that represents the perimeter, in centimeters, of the triangle is (16.2t+3.4u+2.9)cm</em>
