Answer:
C
Step-by-step explanation:
Since every side of ΔABC is dilated by 3, or triple the size
We multiply every length of ΔABC by 3
But the length of DF and FG are already done for us but DG is not, which is essential to finding the answer
7 x 3 = 21
DG = 21
5/7 = 15/21
5 ÷ 7 = 0.71
15/21 = 0.71
5/7 = 15/21
F(8)=4(8)-2+7(8)
f(8)=32-2+56
f(8)=86
f(-5)=4(-5)-2+7(-5)
f(-5)=-20-2+2
f(-5)=20
f(0)=4(0)-2+7(0)
f(0)=0-2+0
f(0)=-2
Answer:
94 3/24
Step-by-step explanation:
86 14/24 + 7 13/24 = 86 + 7 + 14/24 + 13/24
= 93 + (14+13)/24
= 93 + 27/24
{here 27/24 is improper fraction. so convert to mixed fraction }
= 93 + 1 3/24
= 94 3/24
C. Two pairs of corresponding angles will lock in the 3rd angel and triangles will be similar
Having two pairs of corresponding sides does not guarantee similar triangles. See the attachment.
Since a^2 - b^2 = 1, the value of y = 1 because x=1 and 1^2 - 1^2 = 0
